The <b>Mesh Information</b> dialog box provides three tab pages:
-- <b>\ref advanced_mesh_infos_anchor "Base Info"</b> - to show base
-information about the selected mesh object
+- <b>\ref advanced_mesh_infos_anchor "Base Info"</b> - to show
+ base and quantitative information about the selected mesh object.
- <b>\ref mesh_element_info_anchor "Element Info"</b> - to show
-detailed information about the selected mesh node or element.
-- <b>\ref mesh_addition_info_anchor "Additional Info"</b> - to show additional information available
-for the selected mesh, sub-mesh or group object.
+ detailed information about the selected mesh nodes or elements.
+- <b>\ref mesh_addition_info_anchor "Additional Info"</b> - to show

+\anchor dump_mesh_infos
+The button \b Dump allows printing the information displayed in the
+dialog box to a .txt file. The dialog for choosing a file also allows
+to select which tab pages to dump via four check-boxes. The default state
+of the check-boxes can be changed via \ref mesh_information_pref "Mesh information"
+preferences.
\anchor advanced_mesh_infos_anchor
<h2>Base Information</h2>
The <b>Base Info</b> tab page of the dialog box provides general
information on the selected object - mesh, sub-mesh or mesh group:
name, type, total number of nodes and elements separately for each
-type: 0D elements, edges, faces and volumes.
+type: 0D elements, edges, faces, volumes, balls.

\anchor mesh_element_info_anchor
<h2>Mesh Element Information</h2>
-The <b>Element Info</b> tab page of the dialog box gives basic
-information about the type, coordinates and connectivity of the
-selected mesh node or element.
+The <b>Element Info</b> tab page of the dialog box gives detailed
+information about the selected mesh node(s) or element(s), namely:
-\image html eleminfo1.png
-<center><em>"Element Info" page, node information</em></center>
+- For a node:
+ - Node ID;
+ - Coordinates (X, Y, Z);
+ - Connectivity information (connected elements); double click in
+ this line reveals information about these elements;
+ - Position on a shape (for meshes built on a geometry);
+ - Groups information (names of groups the node belongs to).

+- For an element:
+ - Element ID;
+ - Type (triangle, quadrangle, etc.);
+ - Gravity center (X, Y, Z coordinates);
+ - Connectivity information (connected nodes); double click in
+ a line of a node reveals the information about this node;
+ - Quality controls (area, aspect ratio, volume, etc.);
+ - Position on a shape (for meshes built on a geometry);
+ - Groups information (names of groups the element belongs to).

+The user can either input the ID of a node or element he wants to
+analyze directly in the dialog box or select the node(s) or element(s) in
the 3D viewer.
+If <b>Show IDs</b> is activated, IDs of selected nodes or elements are
+displayed in the 3D viewer.
+
+\note The information about the groups, to which the node or element belongs,
+can be shown in a short or in a detailed form. By default, for performance
+reasons, this information is shown in a short form (group names
+only). The detailed information on groups can be switched on via
+\ref group_detail_info_pref "Show details on groups in element information tab"
+option of \ref mesh_preferences_page.

\note For the performance reasons, the number of underlying nodes is
computed only by demand. For this, the user should press the "Compute"
button (see picture). Also, the number of underlying nodes is
automatically calculated if the size of the group does not exceed
-the "Automatic nodes compute limit" set via the "Mesh information"
-preferences (zero value means no limit).

+\anchor mesh_quality_info_anchor
+<h2>Quality Information</h2>
+
+The <b>Quality Info</b> tab provides overall information about mesh quality controls on the selected object - mesh, sub-mesh or mesh group:
+- Name;
+- Nodes information:
+ - Number of free nodes;
+ - Maximal number of elements connected to a node;
+ - Number of double nodes;
+- Edges information:
+ - Number of double edges;
+- Faces information:
+ - Number of double faces;
+ - Number of over-constrained faces;
+ - Aspect Ratio histogram;
+- Volume information:
+ - Number of double volumes;
+ - Number of over-constrained volumes;
+ - Aspect Ratio 3D histogram.

+\note It is possible to change <b>Double nodes tolerance</b>, which
+will be used upon consequent pressing \a Compute button. The default value
+of the tolerance can be set via the
+\ref dbl_nodes_tol_pref "Quality controls" preferences.
+
+\note For performance reasons, all quality control values for big
+meshes are computed only by demand. For this, press the \a Compute
+button. Also, values are automatically computed if the number of nodes
+/ elements does not exceed the
+\ref auto_control_limit_pref "Automatic controls compute limit" set
+via the \ref mesh_information_pref "Mesh information" preferences
+(zero value means that there is no limit).

+built with Plot 2D Viewer (option SALOME_USE_PLOT2DVIEWER is ON when
+building GUI module).
